Manufacturing method

of nylon cord fabric Nylon cord fabric is an important raw material for the production of chemical products. It is widely used in rubber products such as tires, tapes, conveyor belts, etc. as reinforcing materials to improve the strength and wear resistance of products. This article will introduce the manufacturing method of nylon cord fabric in detail.

1. raw material preparation

manufacturing nylon cord fabric is the main raw material of nylon yarn, generally used nylon 6 or nylon 66. In the preparation process, a certain amount of antioxidants, lubricants, antistatic agents and other additives need to be added to improve the performance of nylon yarn.

2. tow drafting

the raw material nylon yarn through the drafting equipment, stretched to a certain multiple, increase its strength and elastic modulus, ready for the subsequent weaving process.

3. Weaving

Nylon cord fabric is generally woven by looms, and the commonly used looms are air-jet looms and rapier looms. In the weaving process, it is necessary to adjust the parameters of the loom according to the product requirements to ensure that the thickness, density, and fabric structure of the cord fabric meet the requirements.

4. heat treatment
After the
weaving is completed, the cord fabric needs to be heat treated to eliminate internal stress and improve dimensional stability. Heat treatment generally uses high-temperature setting equipment to heat the cord fabric to a certain temperature, keep it for a certain time, and then cool it to room temperature.

5. post-treatment
After the
heat treatment is completed, the cord fabric needs to be post-treated, including cleaning, drying, coiling and other processes to ensure product quality and facilitate storage and transportation.

6. quality inspection

manufactured nylon cord fabric needs quality inspection, including strength, elongation, thickness, density and other indicators of the test, to ensure that the product meets the relevant standards and customer requirements.

In short, the manufacture of nylon cord fabric needs to go through the processes of raw material preparation, tow drafting, weaving, heat treatment, post-processing and quality inspection, and each process needs to strictly control the process parameters to ensure product quality.
